basedir(PathType, Application, Opts) -> file:filename_all()
OTP 19.0basedir(PathsType, Application, Opts) -> [file:filename_all()]
OTP 19.0
类型:
PathType = basedir_path_type()
PathsType = basedir_paths_type()
Application = string() | binary()
Opts = basedir_opts()
basedir_path_type() =
user_cache | user_config | user_data | user_log
user_cache | user_config | user_data | user_log
basedir_paths_type() = site_config | site_data
返回给定类型的一个或多个合适的路径。如果Opts中未设置os,则该函数将默认为本机选项,即'linux'、'darwin'或'windows',如os:type/0所理解的那样。任何未识别为 'darwin' 或 'windows' 的内容都会被解释为 'linux' 。
选项'author' 和'version' 仅与'windows' 选项模式一起使用。

user_cache该路径位置适用于本地计算机上的临时数据文件。
